In some embodiments, the patient is treated with a reduced dose of the CYP3A4 substrate drug for about 2-42 days.
1. A method of treating lung cancer in a patient in need thereof with an antineoplastic drug which is a CYP3A4 substrate, wherein the patient is treated with posaconazole, comprising:
(a) stopping posaconazole treatment;
(b) delaying administering, for at least 9 days after stopping posaconazole treatment, a dose of the anti-neoplastic drug that the patient would have received based on the patient's age and condition of the patient had not been treated with posaconazole; and then
(c) administering the anti-neoplastic drug.

4. The method of claim 1 , wherein said administering in step (c) is 9-21 days after stopping posaconazole in step (a).
5. The method of claim 1 , wherein said administering in step (c) is 9 days after stopping posaconazole in step (a).
6. The method of claim 1 , wherein said administering in step (c) is 10 days after stopping posaconazole in step (a).
7. The method of claim 1 , wherein said administering in step (c) is 11 days after stopping posaconazole in step (a).
8. The method of claim 1 , wherein said administering in step (c) is 12 days after stopping posaconazole in step (a).
9. The method of claim 1 , wherein said administering in step (c) is 13 days after stopping posaconazole in step (a).
10. The method of claim 1 , wherein said administering in step (c) is 14 days after stopping posaconazole in step (a).
11. The method of claim 1 , wherein said administering of step (c) is at least 21 days after stopping posaconazole in step (a).
12. The method of claim 1 , wherein said administering in step (c) is 9-42 days after stopping posaconazole in step (a).
13. The method of claim 1 , wherein the lung cancer is non-small cell lung cancer.
14. The method of claim 1 , wherein the anti-neoplastic drug is selected from the group consisting of erlotinib, crizotinib, dabrafenib, brigatinib, lorlatinib, and trastuzumab deruxtecan.
